USB
The GSM Relay is a GSM based controllable module from your cell phone with Two (2) inputs and one (1) Relay
output. The main idea for the unit was to reset Router boards on a wireless network which became inaccessible
through the wireless Network however it can be used for lots of different applications, control any electrical
equipment, monitor the voltage of your battery backups, alarm system etc.
Custom code can be written for customers with different needs over the standard program loaded on date of
purchase of the module , customers can re-program the new code onto the device themselves via the on board USB
connection. The unit feature a “SELF PROGRAMMABLE” micro Processor (Explained later in the manual)
The module reacts on specified command SMS’s received, returns SMS’s to the user and can also alert the user if
anyone of the 2 inputs changes state.
2 : User Instructions
The GSM Relay comes pre-programmed with our standard version of the GSM Relay Software.
Insert a SIM card on the bottom of the board into the SIM card holder and secure the socket, the SIM card pin
request must be disabled. Save the phone number of the SIM card to your phone.
Powering up the board: connect 12 to 28 VDC on the 2 way terminal marked “ POS NEG “ 12-24vdc – usually from
backup batteries or a power supply if there is no battery backup system.
The Status LED on the board will light up to indicate that the GSM engine have booted up.
After about 3 to 5 seconds the network LED on the board will start flashing indicating a successful connection to a
GSM network and after about 5 seconds the network led should blink slowly to indicate that it is in sync with the
network and the GSM Relay is now ready to use.

INPUTS:
The 2 Inputs is potential free inputs, no voltages should be injected here.
The user must ensure potential free contacts on inputs – eg: Relay contact or switch or jumper
The board source a negative supply for the input – board marked (NEG IP1 - NEG IP2)
As soon as the unit is powered up it takes a sample of the input status (contact between NEG and IP1 and NEG and
IP2) and saves this as the normal state. If Auto reply jumper J9 is installed, as soon as the status of any input changes
an SMS will be send to notify the user about the change only if the change in input state persists longer than 10
seconds, an SMS will be send every time the status of any input changes for longer than 10 seconds.
If Auto Reply jumper J9 is not installed no SMS’s will be send on input status change.
____________________________________________________________________________________________
Cell Number
After power up the GSM Relay send a sms with text “save” to the units number. The number will be saved as the
primary number and a sms with text “number saved” will be returned to your phone. The primary number have full
control on the unit to change input names , add and remove numbers etc.
Send sms with text “add082(number)” to add a secondary number to the unit. SMS with text “sec num saved” will
be returned to your phone and to the secondary phone number.
The primary number have full control on the unit and can send commands etc to the unit without the secondary
number being notified. Any status request or commands list request from the secondary number will result in a sms
only to the secondary number , but any operational commands like “reset” or “on” etc will result in a sms to the
Primary and secondary number.
Inputs
Standard the unit will refer to “Input1” and “Input2” in a SMS, the user can change this by sending the following
I1xxxxxxxxxx ( Capital letter i with a 1 +10 user characters) eg : I1eskom_ _ _ _ _( _=5spaces at the end) to fill the
string as eskom is only 5 characters
Or eg: I1generator_ ( _1space at the end)to fill the string – generator is 9 characters
Follow the same sequence for Input 2 renaming
